Clinton Township, which included what is now Irvington, Maplewood and parts of Newark and South Orange, was created on April 14, 1834. The area was known as Camptown until the mid-1800s. In 1850, after Stephen Foster published his ballad, Camptown Races, residents were concerned that the activities described in the song would be associated with their community. The town was renamed, Irvingtown, in honor of Washington Irving.
